In order to be able to set up in such a way that all the slides
fit between the light sensor and the LED without having to shift
the mounts, the 5 slides are first held between the light sensor
and the tube on the LED and the mounts are pushed together
accordingly.
How id light attenuated when passing through substances? When
light passes trough a substance or liquid the intensity is
attenuated. This attenuation can be demonstrated by means of a
light sensor. In this experiment the number of absorbing layers
(grey filters) is modified and the light intensity is measured.
Eventually you will develop a formula in this experiment for the
reduction in intensity as a function of the thickness of the layer
that the light passes through. Note: The variation in the number of
grey filters can be interpreted as a variation in the thickness of
a single body.
